... For things like batteries, we specify the potential difference between the contacts (poles) on the batery. So a "D-cell" has a rating of 1.5 volts which means that every 1C of charge (electrons) that moves from the negative side of the cell to the positive side will do 1.5 Joules work. 1. Potential ...
